Nuclear Material Security Monitoring using Multisensor Integration

The security of nuclear material in a nuclear installation is determined by how far the installation can guarantee the fuel remains at a designated location. This paper developed a methodology of monitoring nuclear material in an installation by integrating multiple sensors in an integrated manner. By using several kinds of sensors, the certainty will remain monitored nuclear material movement for decision making will be more assured. Decision-making on information systems is obtained based on several levels of information. The first level is obtained based on the integration of the information of several CCD camera sensors and/or nuclear detector mounted distributed around the object. The second level is achieved based on image analysis and data operation. While the third level is obtained based on the understanding of perception at the third level of abstraction. The integration of some of these sensors can be represented using the Wavelett method. The integration of some information obtained from multiple sensors equally or differently sequentially will be able to reliably effect the movement of nuclear material movement in different spaces. Sequential information may be completed with a control area boundary, so that when the controlled area boundary is violated will provide flashing mode on the annunciator or alarm on the console. Thus the security of nuclear material will be monitored properly. (author)
